Spinal Cord
The spinal cord transmits sensory reception from the peripheral nervous system. It also conducts motor information to the body's skeletal muscles, cardiac muscles, smooth muscles, and glands. There are 31 pairs of spinal nerves along the spinal cord. These nerves each contain both sensory and motor axons. The spinal cord is protected by vertebrae, and connects the peripheral nervous system to the brain, and it acts as a "minor" coordinating center.
Brain
The brain apprehends signals from the spinal cord as well as the olfactory nerves (or the first cranial nerve) and optic nerves. It allows the body to function. The brain is protected by the skull; however, if the brain is damaged, the results to the human body can be very consequential.
